FREDRICK HAGEN, OF BELVIDERE, ILLINOIS.

FEEDER FOB CORN-SHREDDERS.

To all whom t may concern:

Be it known that I, Fnnnnrci; HAGEN, a citizen of the United States,residing at Belvidere, in the county of Boone and State of Illinois,have invented certain new and useful Improvements in Feeders for Gorn-Shredders, of which the following is a specication.

The object of this invention is to construct a feeder for corn Shreddersin which t-wo distributing heads are rotated at different speeds inorder that the upper stratum of stalks may be held back by one headwhile the lower stratum of stalks will be carried toward the snappingrolls.

In the accompanying drawings, Figure 1 is a side elevation of a shreddercontaining my improvements. Fig. 2 is an elevation of the reverse sideto that shown at Fig. 1. Fig. 3 is a vertical section on dotted line b bFig. 4. Fig. 4 is a plan view on dotted line a a Fig. 3, in which thetop board is removed, and the bearing for the upper snapper roll is insection. Fig. 5 is a perspective view of a portion of one of thehexagonal sections of a distributing head.

The main frame of the shredder comprises the sides 1 connected in thisinstance by the cross-bars 2. An endless carrier 3 is supported by ashaft 4, and moved by the sprocket wheel 5. To one end of this shaft 4is secured a sprocket wheel 6. Two snapping rolls 7 are supported to berotated by any suit-able connection with the main drive, which is notdeemed necessary to show.

A band cutter comprises a shaft 8 to which are connected a plurality ofcutter heads 9. A sprocket wheel 10 is secured to one end of this shaftand a pulley 11 is secured to the other end of the shaft. These cutterheads are supported to rotate in the direct-ion indicated by the arrowon Fig. 3.

A distributing head is located adjacent to the delivery end of theendless carrier 3, and comprises the hexagonal center 12 secured to ashaft 13 to be rotated thereby. To each of the faces of the center 12 issecured asaw toothed plate 14. The saw teeth of these plates areinclined backward with respect to the direction of rotation. To one endof the shaft 13 is secured a sprocket wheel 15, and to the other end ofthis shaft is secured a pulley 16, a linked chain 17 passes over thesprocket wheels 6 and 15 and under an idler 18. A sprocket wheel 19 issecured to the shaft 13 and is Specification of Letters Patent.

rotated by the linked chain 2O moved by a connection with the primemover.

Another distributing head is located above the distributing head justdescribed and between it and the delivery end of the endless carrier.This distributing head comprises a hexagonal center 21 secured to ashaft 22. To each of the faces of this hexagonal center 21 is secured asaw-toothed cutter 23 which is located tangential with respect to theshaft 22 and forms a continuation of the face, and extends rearwardlywith relation to the direction of rotation of the complete head as shownby the arrow on Fig. 3. To one end of the shaft 22 is secured a sprocketwheel 24 and a chain belt 25 connects the sprocket wheels 10 and 24. Acrossed belt 26 connects the pulleys l1 and 16, and as pulley 16 is thedriver, the band cutters will be rotated in a direction opposite to thelower distributing head.

The shaft 22 is mounted in pivotal bearings 27 which are made adjustableand held when adjusted by the straps 28 provided with holes 29 throughwhich a bolt 30 may be passed and connecting it with the main frame.

The shaft 8 is mounted in pivotal bearings 31 which are made adjustableand held when adjusted by the straps 32 provided with holes 33 throughwhich a bolt 34 may be passed and connecting it with the main frame. Bymaking the shaft 8 vertically adjustable, the band cutters supported byit may be held atdifferent distances above the endless carrier 3, and bymaking the shaft 22 vertically adjustable, the distributing headsupported by it may be held atdifferent distances above the distributinghead supported by the shaft 13.

In use the distributing heads, band cutter, endless carrier and snappingrolls are moved in the direction indicated by the arrows shown at Fig.3. The corn stalks are dropped onto the endless carrier and pass underthe band cutters which sever the bands, thereby liberating the stalksand permitting them to spread out. As the stalks pass between thedistributing heads and as the lower head rotates faster than the upperhead, the lower stratum of stalks will be moved faster than the upperstratum, thereby presenting the stalks to the snapping rolls in a thinsheet or layer.

By locating the saw teeth 14 of the lower distributing head at theangle' shown, they will more fully free themselves from the stalks.

I claim as niy invention.

l. In a corn shredder, the combination with a conveyer, of upper andlower rotary distribnters associated with the delivery end of theconveyer, one being a delivery distributer, the other a retardingdistributer, said dstributers having projecting teeth, the teeth of theretarding distributer being tangential to its axis of rotation, theteeth of the delivery distributer being more nearly radial, and meansfor rotating the distributers.

2. In a corn shredder, the combination with a conveyer, of upper andlower rotary distributers associated with the delivery end of theconveyer, said distrbuters each comprising a polygonal body, and bladeswith saw teeth secured to the different: faces of the bodies, the teethof the blades of the upper body being disposed substantially in the sameplanes as the blades having such teeth and those on the lower body beingset at an angle to the blades and more nearly radial to the axis ofrotation of the body, and means for rotating the distributer in oppositedirections and at dlerent rates of speed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
